RIFLE Filed July 16, 1935 2 Sheets-Sheet 2 Inventor Patented Nov. 2, 1937 4 Claims.

This invention appertains to new and useful improvements in fire arms and more particularly to a novel bolt action for rifles.

The principal object of the present invention is to provide a bolt action wherein the usual actuating lever carries a safety catch which automatically locks the bolt when the lever is in bolt locked position.

The principal object of the invention is to simplify rifle mechanism by providing a safety catch directly in conjunction with the bolt lever so that in the normal locked position of the lever, the safety catch is in effect and when the lever is lifted to a lateral position, the safety catch is off and the firing pin ready to be actuated by the trigger.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 is a top plan view of the breech portion of a rifle showing the bolt lever about to be locked.

Figure 2 is a side elevational view of the breech portion of a rifle showing the lever thereof in the position shown in Figure 1.

Figure 3 is a top plan view of the breech portion of a rifle showing the lever of the bolt in a lateral position, before disposition to a safety position.

Figure 4 is a fragmentary longitudinal sectional View of the breech portion of the rifle showing the bolt lever in locking position along with the safety catch.

Figure 5 represents a fragmentary detailed sectional view taken substantially on line 5-5 of Figure 3.

Figure 6 represents a bottom plan view of the bolt structure.

Figure 7 represents a side elevational view of the butt end of the bolt.

Figure 8 represents an end elevational view of the structure shown in Figure '7,

Figure 9 represents a perspective view of the bolt structure.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figures 1 and 2 that numeral 5 represents the usual barrel of the rifle while numeral 5 represents the breech portion in which the bolt 1 slides.

In the usual way, the rear end of the bolt I is internally threaded to receive the threaded tubular extension 8 on the head structure 9. The firing pin it extends through the head 9 and tubular extension 8 and is provided with an enlargement H at its rear end slidable into the socket I2 in the head 9. The pin IE1 has an opening it transversely therein for receiving the finger I l pivotally connected to the lever [5 of the bolt. This lever is pivotally connected as at [6 between two ears H on the bolt 1. A spring projected'pawl It serves to connect the head 9 with the barrel 1, so that only when the bolt is projected to the position shown in Figures 1 and 2 is the ball l8 compressed so that the bolt 1 is freed from the head 9 in which condition the bolt is free to be rotated so that the spring l9 which is interposed between the tubular extension 8 and the forward end of the bolt 1 is compressed. When this action takes place, of course the usual trigger is in position to hold the pin I0 under tension and only when this trigger 20 is pulled and the pin released, can the rifle be fired.

However, it can be seen, that in order to remove the bolt 1, the lever I5 must be swung to a vertical position and then pulled rearwardly. The operation of loading and cooking the trigger as well as applying the safety catch M is all taken care of by continual motion of the lever 15. In other words, the lever 55 is swung from the vertical position, when the bolt has been slid in, as shown in Figure 2, to the lateral position shown in Figure 3, in which position the trigger is cocked and by disposing the lever l5 rearwardly to the dotted line position shown in Figure 3, the safety catch it is disposed into the firing pin it so that the firing pin cannot be moved when the trigger is pulled.

As can be seen in Figure 7, a spring projected pin 2i is employed and is essential for taking the bolt apart. In disassembling the bolt the pin must bepressed down and held firmly until the bolt is released from the rearward position. Then the trigger is pulled and the firing pin remains cocked, and only in this position can the bolt be taken apart by hand.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In a. fire arm, a bolt, a firing pin operative in the bolt, a bolt shifting lever on the bolt, said bolt having an opening in one side thereof, said pin an opening therein registerable with the opening in the bolt when the pin is in cocked of, said pin having an opening therein registerable with the opening in the bo ltiwhen the pin is in cocked position, said lever being pivotally connected to said bolt to swing longitudinally thereof, and a catch on the leven;.to enter the registering opening when the lever is swung to a position substantially parallel to the.

bolt, said catch having a head,,said pin haying a shoulder in its opening against which the catch engages. 1

3. In a fire arm, a bolt, a firing pin operative in the bolt, a bolt shifting lever on the bolt, said bolt having an opening in'one side thereof, said pin having an opening therein registerable with the opening in the bolt when the pin is in cocked position, said lever being pivotally connected to said bolt to swing longitudinally thereof, and a catch on the lever to enter the registering opening when the lever is swung to a position substantially parallel to the bolt, said catch having a head, said pin having'a shoulder in its opening against which the catch engages, and spring means associated with the catch for tensionally holding its head against the shoulder.

4. In-a fire-arm, a bolt, a firingpinoperative the bolt, a bolt shifting lever on the bolt, said bolt having an opening in one side thereof, said pin having an opening therein registerable with the opening in the bolt when the pin is in cocked .position, said lever being pivotally connected to said pglt joswing longitudinally thereof, and a catch on the lever to enter the registering open- .ing when;the-.-lever.is swung to a position substantially parallel to the bolt, and a spring projected pin on the bolt for engaging the firing pin to ,permit the bolt to be disassembled. l
